AP Physics C Mechanics: SHM & Gravitation
Oscillations and gravitation on AP Physics C Mechanics often use differential equations for SHM and inverse-square reasoning for orbits — confirm exact scope in your Course and Exam Description.
Hub: AP Physics C Mechanics · Energy · Calculus.
Simple harmonic motion
| Concept | Notes |
|---|---|
| Restoring force | F ∝ −x or similar |
| Energy | KE ↔ PE in oscillation |
| Period | Spring vs pendulum formulas in CED |
| Calculus | x(t) = A cos(ωt + φ) from DE if required |
Link to energy methods when asked for maximum speed at equilibrium.
Gravitation
- Newton’s law of gravitation — field and potential ideas per syllabus.
- Circular orbit problems — tie to kinematics and centre of mass.
